"'Be it known that I MARK A. Bnowx, a

States, residing at V Ghattanoo at, in the county of Hamilton and State of ennessee, have inventeda new and useful Air-Brake Coupling, of which a the following isa specification.

The invention relates to improvements in air-- brake couplings.

The object of the present invention is to 1 improve the construction of air brake coupling-wand to rovi'de a sim )le, inexpensive I and eiiicient airhrake coupling. capable of coupling and uncoupling automatically on 1'5 l.ll,\0S as well as on straight'tracks, and equipped with meansf or firmly locking" two [con ilingheads together and for automaticallvy linlorglting the same to permit the coup- 'lcimheads to separate without strain. when the cars to which they areconnected are'un- G l. 5-; Another object of the iri'ig ehtion is to yield ably mount the coupling hands so as afford the necessary play and to enable freight 2'5fiand passenger-equ pments to couple inter- Vith these and other ohj ccts in. View, the

7 passenger our .open r'e'ctan with 'the coupling front end wall of the frame 2.

'der to provide a place for invention consists-in the construction and 1 novel comhi'nation of parts hereinafter fully 0' described, illustrated in theaccompanying drawings,

and pointed out in the 1 claims hereto appended; it being understood that various changes in the form, -proportimi, size wand'minpr dctails of construction, within the the claims, maybe resorted to with, 1 out tdepartin from the spirit or sacrificing .5111 of the at rantages of the invention.

The tubular are provided with inextensions or nozzles termediate. tapered portions 25, and they with gaskets 27 a and 28, arranged to have cylindrical ,terminals 26 ada ted to fit in the sockets 22, 23 and 24, whic are of a depthlto receive the cylindrical terminals of the nozzles, the tapered portions bein arranged to coiiperate with the side wal s of the sockets -to form air tight connections.

The nozzles and the sockets may be eguipped orm an When two air tight-joint or connection.

The V- shaped conduits of the cotipling heads provide two 0 )posite uninterrupted passages for the air an afford a free passage of the same through the coupling, so thatthe efficiency of the air brake is not im aired, but is facilitated by the coupling, t1e-double passage permitting the air to ass through the coupling practically as freely as ifa straight pipe connection were employed.

The air brake coupling head is mounted in a hanger 39, consisting of a box-like sup-' port sus ended from the car coupling by ianger -l ops .40, embraced and suitably se-- cured to the draw head 41 of the car coupler, The hanger loops are preferably rectangular and receive the draw head 41 and the han er 39, and they are braced by inclined meta lic straps 42, arranged in pairs and crossing each other at. the sides of the hanger, as clearly illustrated in Fig. 1 of the drawings. The'hanger is provided with a horizontal bottom and parallel sides, 'and the head is equipped with isposed longitudinally and secured at the center to the outer faces of the sides of the frame 2 and having free terminals engaging the inner faces of the sides of the hanger, as clearly shown in Fig. 3 of the drawings. These springs yieldabl' maintain the framesin spacedrelation wit the side walls of the hanger, and when two cou led and ,locked, they emit a horizonta play or nwyement. cit e parts.- The air bra e couplings by being suspended fromthe car couplers partake of the lateral and longitudinal movement thereof and the are also capable of independent longitu inal movement throu h the coiled springs 16.
